About Base64 Tools

Base64 Tools is a free collection of browser-based utilities for working with Base64 data: converting documents and images, inspecting and validating encoded content, and moving between Base64, hex and Base64URL formats.

Everything on this site runs locally in your browser. Files you open and text you paste are processed on your own device — they are never uploaded, never sent to an API and never stored anywhere else. There is no account to create and nothing to sign up for.

base64tools.online is operated by an individual developer.

Privacy is not a marketing line here; it is how the site is built. Your files and input never leave your device, and we use privacy-respecting analytics — two of them cookie-free — only to understand overall site usage. Analytics cookies are off unless you accept them, and you can change that choice at any time. You can read the full details on the Privacy Policy page.

Spotted a mistake, a broken conversion or something that could be better? Corrections and feedback are welcome at support@base64tools.online.
